Person detained and released in Guthrie investigation

Wednesday marks Day 11 in the search for Nancy Guthrie, the 84-year-old mother of "Today" show host Savannah Guthrie. Guthrie was taken from her Tucson-area home reportedly against her will. This comes as a search warrant was conducted in Rio Rico, Arizona, located an hour south of Tucson at around 9 p.m. on Tuesday after a person of interest was detained and then released after questioning. LiveNOW’s Shawna Khalafi is speaking with former Sheriff's Detective and Investigator, Jamie Copenhaver, as the Pima County Sheriff's Department says they've received nearly 18,000 calls since Feb. 1 regarding the Guthrie investigation.
